If you are speaking that the world is running out of phosphate? I cannot quantify this with my own research, However if you are talking that soil is phosphate limited I would tend to agree however this is due to non sustainable land practices. Not completing the nitrogen cycle and not allowing bacteria to work as it had for eons.

Consider that in the great plains for instance here.. Buffalo roamed and ate and did not degrade the land too much. Wolves kept population in check however there is one minor difference. Buffalo and Wolf's crapped and pissed all over the place replenishing the soil of the nutrients brought out. This was in effect completing the nitrogen cycle. Is this what you are asking? As in modern Agriculture it seems quite nice to flood the fields with water and allow that to run off and drain into the ocean without a care and thus promotes deadzones and flushes what was once good fertilizers out into the sea never to be recovered.

I hope this helps some.
